I'm guessing that the injury clause was made intentionally vague - I've negotiated enough athlete contracts to know that lawyers don't write anything without a reason. Seems like both the Bills and Tyrod have arguments to make regarding the clause...
There is also this line:
Which says to me that, like all contacts, this has some wins for the Bills (and Ty) and some potential losses for the Bills (and Ty) - so maybe the Bills aren't idiots, they're just adding to a contract what they need to, to get it over the finish line. It also says to me they use the euro spelling of unfavorable.
Maybe the one eye opener for me was, this says that if the Bills cut Ty and he's still injured he gets 27.5MM. I thought that if he was still injured by March whatever, the Bills would have to pick up the contract and he'd still be on the team.
Of course, if they KNOW he's not going to be ready by the cut date and they're going to owe him $27MM to cut him, they might as well just pick up the deal regardless. As the article says a few times, it's a middle of the pack deal...
Which actually means American taxpayers will pay for it, but don't worry Mexico will pay us back!
